In this paper an attempt for review of the most popular directional transforms is made in relation to their applicability in image coding along with some directions for future improvement of their incorporation into complete compression algorithms. Some comparison considerations are given for the DDCT, DWHT, DDWT and others based on image quality, execution time and memory efficiency when applied for image compression. These transforms are considered even more effective if used in combination with some spectral coefficients rearrangement as suggested for further elaboration.
